SHAFT-COUPLING.

SPECIFICATION forming part Of Letters Patent NO. 674,479, dated May 21, 1901.

Application filed October 19, 1900- Serial No. 33,638. (N model.)

' is a specification.

My invention relates to improvements in shaft-couplings of the class set forth in my previous patent, No. 441,445, of November 25, 1890, and in my pending application, Serial No. 586,354, filed April 4, 1896, and has for its object the product-ion of a device which is cheaply manu factn red and is particularly effective and durable in use; and to this end it consists, essentially, in the combination, construction, and arrangement of the outer shell and the inner sleeve of the shaft-coupling, as

hereinafter fully described, and pointed out in the claims.

part of this specification, in which like letters indicate corresponding parts in all the views.

Figure 1 is a longitudinal vertical sectional view of my improved shaft-coupling, its inner sleeve being shown in elevation and as operatively engaged with a shaft. Fig. 2 is an end view of a portion of my improved shaft-coupling. Figs. 3 and 4 are transverse and longitudinal sectional views taken, respectively, on lines 3 3 and 4 4, Figs. 1 and 3, the shaft being omitted in Fig. 4. Fig. 5 is a plan view of the inner sleeve of my shaftcoupling, shown as split lengthwise and as folded fiat.

AA and B B are end and intermediate sections forming the outer shell of myimproved shaft-coupling, and O is a shaft-receiving sleeve arranged within said shell. The sections A A and B B are formed with conical tapering inner faces a and apertn res a and are drawn toward each other by clamping means, as bolts D. As best seen in- Fig. 1, a number of the apertures a in the intermediate sections B B are of greater size than the remaining apertures 01. in said intermediate sections. Part of the bolts D are passed through the apertures a of greater size in one of the intermediate sections,andcorrespondingends thereof are passed through the apertures a in the adjacent end section and are engaged with said end section, and their opposite ends are passed through the apertures a of less size in the other intermediate section and are engaged with said other intermediate section, and the remaining bolts D are passed through the apertures a of greater size in said other intermediate section, and corresponding ends thereof are passed through the apertures in the adjacent end section and are engaged with said end section, and their opposite ends are passed through the apertures of less size in the former intermediate section and are engaged with said former intermediate section. By this construction and arrangement of the apertures a, and the bolts D it is possible, without liability of binding of thebolts, to use comparatively short bolts for effectively drawing the intermediate sections toward each other and drawing the end sections toward the outer sides of the intermediate sections.

The inner sleeve 0 encircles the divisions of the shaft D to be coupled, is preferably composed of spring metal, and is formed with conical or tapering ends which engage the inner faces a of the sections A A and B B. Said sleeve is also formed with longitudinal substantially equidistant slots 0, extending from one of its end faces into proximity to the opposite end face and with a plurality of additional substantially equidistant longitudinal slots 0', extending alternately between the slots cfrom said opposite end face into proximity to the former end face. The slots 0 divide the sleeve 0 into a number of yielding parts o which taper or decrease in thickness toward the ends of the sleeve, are connected together at one end of the sleeve, and engage the faces a of the sections A A and B B and the periphery of the shaft D, inserted with;

branches to yield independently throughout almost their entire length and to positively and effectively engage and closely fit the divisions of the shaft D.

The construction and operation of my shaftcoupling will now be readily perceived upon reference to the foregoing description and the accompanying drawings.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a shaft-con pling,the combination with an outer shell consisting of intermediate sections movable toward each other, and end sections movable toward the outer sides of the intermediate sections, said sections having tapering inner faces; of clamping means for connecting one of the end sections to the intermediate section adjacent to the other end section, clamping means for connecting said other end section to theother intermediate section, and a shaft-receiving sleeve arranged within the outer shell and provided with movable parts engaged with said inner faces and with the periphery of the shaft inserted within the sleeve, substantially as and for the purpose described.

2. In ashaft-coupling, the combination with an outer shell consisting of end and intermediate sections having tapering inner faces, bolts passed through one intermediate section and having corresponding ends engaged with the adjacent end section and their opposite ends engaged with the other intermediate section, and bolts passed through said other intermediate section and having corresponding ends engaged with the adjacent end section and their opposite ends engaged with the former intermediate section; of a shaft-receiving sleeve arranged within the outer shell and provided with movable parts engaged with said inner faces and With the periphery of the shaft inserted within the sleeve, substantially as and for the purpose specified.

3. In ashaft-coupli-ng,the combination with an outer shell consisting of end and intermediate sections having tapering in ner faces and apertures, a number of the apertures in the intermediate sections being of greater size than the remaining apertures in said intermediate sections, bolts passed through the apertures of greater size in one intermediate section and having corresponding ends passed through the apertures in the adjacent end section and engaged with said end section and their opposite ends passed through the apertures of less size in the otherintermediate section and engaged with said other intermediate section, and bolts passed through the apertures of greater size in said other intermediate sections and having corresponding ends passed through the apertures in the adjacent end section and engaged with said endvsection and their opposite ends passed through the apertures of less size in the former intermediate section and engaged with said former intermediate section, of a shaft-receiving sleeve arranged within the outer shell and provided with movable parts engaged with said inner faces and with the periphery of the shaft inserted Within the sleeve, substantially as and for the purpose specified.

a. In a shaft-coupling,the combination with an outer shell consisting of end sections and separable intermediate sections between the former sections, said end and intermediate sections having tapering inner faces, and means for connecting one end section to the intermediate section adjacent to the other end section and for connecting said other end section to the other intermediate section; of a shaft-receiving sleeve arranged within the outershell and havingits opposite ends formed tapering and engaged with the inner faces of the sections, said sleeve being formed with longitudinal substantially equidistant slots extending from one end face into proximity to the opposite end face, and thereby forming a plurality of yielding parts connected together at one end of the sleeve, and being also formed with additional slots extending alternately between the former slots from said opposite end face of the sleeve into proximity to the former end face thereof for dividing said yielding parts into yielding divisions or branches, the divisions or branches of each yielding part being connected together at the free end of said part, substantially as and for the purpose set forth. 7

5. In a shaft-coupling,the combination with an outer shell consisting of end and intermediate sections having tapering inner faces, bolts passed through one intermediate section and having corresponding ends engaged with the adjacent end section and their opposite ends engaged with the other intermediate section, and bolts passed through said other intermediate section and having corresponding ends engaged with the adjacent. end section and their opposite ends engaged with the former intermediate section; of a shaft-receiving sleeve arranged within the outer shell and having its opposite ends formed tapering and engaged with the inner faces of the sections, said sleeve being formed with longitudinal substantially equidistant slots extending from one end face into proximity to the opposite end face, and thereby forming a plurality of yielding parts connected together at one end of the sleeve, and being also formed with additional slots extending alternately between the former slots from said opposite end face of the sleeve into proximity to the former end face thereof for dividing said yielding parts into yielding divisions or branches, the divisions or branches of each yielding part being connected together at the free end of said part, substantially as and for the purpose set forth.

In testimony whereof I have hereunto signed my name, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 5th day of January, 1900.

FRANK SHAW.
